PAPER-WINDER.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed MaySl. 1906. Serial No. 319,565.

T0 all whom it may concern.-

Be it known that I, Jlmins BUTLER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented cer tain Improvements in Paper-'Winders, of which the following is a specification.

My invention relates to certain improvements in winders used in connection with machines for supercalendering paper.

The object of my invention is to so construct a paper-winding machine that the roll of paper need not be taken off the machine and turned, as is customary in machines used in connection with supercalendering-machines.

In the accompanying drawings, Figure 1 is a view of my improved paper-windingmachine; and Fig. 2 is a sectional view on the line 2 2, Fig. 1, showing my improved winding-machine in connection with a series of supercalendering-rolls, the rolls being shown in diagram and the frame in dotted lines.

Supercalendering-rolls are for the purpose of recalendering paper, so as to produce a smooth surface on the paper. The paper is passed through the set of calendering-rolls A, the rolls a a a a of which are metal-faced rolls, and the rolls 1) b b are paper or cotton faced. In the present instance the paper :0 passes over the roll a and between the rolls a b, as indicated in Fig. 2, partly around a roll I), then between it and another roll a, and so on through the machine, and if it is desired to pass the paper through the rolls a second time the roll of paper must be so placed that the same surface will be acted upon by the metal rolls as was previously acted upon.

Ordinary paper-winding machines are so constructed that in order to have the paper pass off the roll in the right direction the filled roll must be removed from the machine and turned end for end and again placed in position, so that the face of the paper to be acted By my invention I avoid the necessity of removing the roll from the machine by providing means for turning the roll and the frame carried by it end for end. This I accomplish in the following manner: B B are the side frames of the windingmachine, on which is mounted a shaft C, having trunnions c c, mounted in bearings on said frames B. This shaft C has a gear-wheel c at one end which meshes with a pinion c on the shaft 0 mounted in a bear- .f provided with h dles 1- turn the shaft C to reverse the position of the spindles D D, upon which the paper is wound, the pin 0, which is connected to the lever 0 is withdrawn from a hole in the gear- Wheel 0, the worm-shaft is turned slowly, turning the shaft 0 and reversing the position of the two spindles D D.

The s indle D is mounted on a frame E, carried y the shaft O, and the spindle D is mounted on a frame E, also carried by said shaft C. On the shaft are projecting hubs e 6, Fig. 2, on which the frames E E are pivoted, the frames being held in position by plates 6 and screws 6 I preferably provide antifriction-rollers 0 between the bearingsurfaces of the two frames E E and the enlarged portion C of the shaft C, so that the frames can be readily turned end for end.

Projecting from each side of the shaft O are bearingsff, in which are mounted bolts These bolts are arranged to be projected into holes in the ends of the frames E E, so as to lock the frames when they are turned into position.

The ends (Z d of the two shafts D D are shaped so that they can be coupled to a driving-shaft and a tension-shaft. The ends are squared in the present instance to fit the couplings.

On the frame Bis a bracket B, on which are mounted two shafts G and H. The shaft G is mounted in bearings at the upper end of the bracket, and the shaft H is mounted in bearings at the lower end of the bracket. Adapted to slide 011 the shaft G is a coupling g, having a socket corresponding in shape to the end of the spindles D D. This coupling can be shifted by means of a lever 9.

On the shaft G is a friction-drum g and adapted to engage the drum is a frictionband 9 The pressure of this band can be regulated so that more or less tension can be applied to the spindle D and the roll of paper thereon. By this means the roll will not unwind faster than the calendering-rolls can take up, and the paper will always be under tension The shaft H is a driving-shaft, having a double-flanged belt-pulley h in the present instance. This shaft 1 1 also has a drivingling is shifted by a ever h is a carrier for a tension-roll which bears ,upon the driving-belt, so as to place more or The tensionless pressure upon the belt. roller is regulated by a shaft i, having a handwheel i. This mechanism forms no part of my invention, as it is commonly used in winding-machines.

The shafts D D are mounted in their frames E E, so that they can be readily removed. The boxes n are made in two parts, one part being removable and connected to a clamp-lever n, so that on moving the lever in one direction the box is closed and on moving in the other direction the box is opened.

The operation of the machine is as follows: The roll of paper as it comes from the machine is placed on a spindle D, for instance, in such position that the paper will unwind from the top of the roll, as indicated in Fig. 2. The paper as then passes between the rolls of the calenders A in the manner shown in said figure, with the one surface of the paper incontact with the metal-faced rollers, and the paper returns to the winding-machine and is wound on the spindle D from the bottom, as indicated. As is required in supercalendering, the paper is passed through the calenderingrolls several times, according to the character of surface re uired, and if the carriershafts C were simp y turned so as to bring the 'roll of paper on the spindle D in the position of the roll of paper on the spindle D the paper would lead off the roll from the bottom instead of the top, which is objectionable, as it would bring the surface to be calendered in contact with the paper-surface of the calendering-rollsinstead of the metal surface. By turning the roll of paper end for end the paper is brought into proper position to lead off, so that the previously-calendered surface will again come in contact with the metal rolls. This is accomplished by simply withdrawing the coupling h and the bolt f, which looks the frame E, carrying the spindle D, then the frame and its spindle is turned end for end on the pivot e, the bolt is thrown forward to engage the frame and lock it in position, then the coupling 9 on the shaft G is withdrawn from the spindle D, and the worm 0 wheels 0 c c are set in motion, so as to turn the shaft 0 and bring the spindle D in the upper position and the spindle D in the lower position. The paper is then wound from the spindle D, passing between the calenderingrolls and wound upon the spindle D, when the above 0 eration is repeated. Thus the spindles D are not removed from the machine, except when the calendering is completed, and considerable delay and the necessity of lifting the heavy load are avoided.

It will be understood that while I have shown power gearing-by which the drivingshaft can be turned it may be turned by hand without departing from -my' invention and power can be applied to the worm-shaft, if desired.
